The VMware credentials type manages access to vCenter credentials.

Applications that access VMware cloud resources need access to VMware credentials. For example, the VMware credential type enables Discovery to explore VMware's vCenter running on a Windows machine to discover ESX machines, virtual machines, and resource pools. The VMware Discovery and automation API (vCenter API) now provides the globally unique serial number for computer CIs. CIM credentials aren’t needed to enable access to each VMware host.
Note: Windows credentials aren’t necessary for vCenter Discovery, when valid VMware credentials are used.
Important: Do not use VMware Type credentials for Orchestration activities that perform work on the individual virtual machines cloned by vCenter (for example, restarting a Linux VM). For these activities, the credential Type depends on the operating system of the virtual machine (either SSH or Windows).
